Rizzuto family is like old time mafia family where the boss role go to father to son and are many marriage between members parents to create blood ties. Beyond this there are more non italians that are more powerful that are considerated to the same level of a capos. So there are a core group of sicilians or italo-canadians and an another core of canadians. Joe Bravo that was killed in Sicily sincerly believed that was made.

IMO Leonardo Rizzuto rules on what remains of the family.
